Electrical Characteristics of a Glow Discharge in Air over the Surface of Aluminum Sulfate Aqueous Solution

Аннотация

The paper presents the current−voltage characteristics, the magnitudes of cathode potential drop, the dependences of the total and specific glow discharge power which is injected into the plasma from the discharge current, as well as the density of electrons in the glow discharge in air at atmospheric pressure with the cathode based on 1−10% solutions of aluminum sulfate in distilled water. The distance between the electrolytic liquid cathode and the metal anode is varied from 1 to 10 mm at an average discharge current of 8−36 mA. The discharge is promising for the synthesis of nanostructures of aluminum and aluminum oxide which are formed when processing the solutions with a glow discharge.
